Exhaust scavenging system for an engine system

An engine system, comprising:

• an engine enclosure;
• an engine enclosed inside the engine enclosure;
• an air intake system including an air filter having a filter element for filtering air;
• an exhaust conduit coupled to the engine and configured to receive exhaust gas discharged by the engine;
• a venturi associated with the exhaust conduit and operating to generate a suction to draw air from the air filter and the engine enclosure;
• and
• a valve system configured to selectively fluidly connect the venturi with the engine enclosure or the air filter, wherein the valve system fluidly connects the venturi with the air filter for facilitating purging of the filter element of the air filter.

A method for operating an engine system, the engine system including an engine enclosed inside an engine enclosure, an exhaust conduit coupled to the engine to receive exhaust gas discharged by the engine, and an air filter having a filter element to filter air being provided to the engine, the method comprising:

• generating a suction by a venturi associated with the exhaust conduit to draw air from the air filter and the engine enclosure, wherein the suction is generated due to passage of exhaust gas through the venturi;
• and
• controlling a three-way valve to selectively control flow of air from the air filter or the engine enclosure to the venturi due to the suction generated by the venturi, wherein
• the three-way valve is moved to a first position to enable the flow of air from the air filter to the venturi for facilitating a purging of the filter element, and
• the three-way valve is moved to a second position to enable the flow of air from the engine enclosure to the venturi for facilitating an inlet of air into the engine enclosure.
